Mounting Options

The T4S/T8S comes with a 1/4" (6 mm) mounting screw insert. This enables it to be mounted onto a number of available products that include a 1/4" (6 mm) mounting screw, including a camera tripod stand.

Mounting the T4S/T8S on a Camera Tripod Stand

1. Extend the camera tripod legs and secure at desired height.
2. Remove the bracket from the top of the camera tripod stand and secure the bracket to the bottom of the T4S/T8S with the screw. Make sure the small indentation on the T4S/T8S and the bump on the bracket are aligned. See Figure 6.
3. Secure the bracket with the T4S/T8S back onto the camera tripod stand. See Figure 8.

WARNING: Do not use the ToneMatch T4S/T8S mixer with a tripod/stand that is unstable. The mixer is only designed for use on a 1/4" screw (6 mm), and the tripod/stand must be capable of supporting a device with a minimum weight of 1.9 kg (4.1 lbs) and an overall size of 214 x 311 x 83 mm (8.4 x 12.25 x 3.25 inches). Using a tripod/stand that is not designed to support the size and mass of the T4S/T8S mixer may lead to an unstable and hazardous condition that could result in injury.

Connecting the T4S via Digital Connection

1. Make sure the L1 Model 1S/II and T4S are powered off and the T4S Master volume control is set to minimum.
2. Plug one end of the ToneMatch cable into the Power port/Digital Main Output R on the T4S. Plug the other end of the ToneMatch cable into the ToneMatch port on the power stand.

Note: To connect the T4S to two L1 Model 1S/II power stands, connect a second power stand to the Digital Main Output L port on the T4S using a ToneMatch cable.

1. Turn on the mixer and then turn on the L1 Model 1S/II power stand.
2. Connect your instruments and adjust levels.
